STEAM Loic-LOADER.

SPECIFICATION'forming part of Letters Patent No. 420,942, dated February11, 1890.

Application led December 31, 1888. Serial No. 295,041. (No model.)

for the purpose which shall be quick and ref liable in its actions. Tothis end I pivot the log-loading lever to a swinging mast and operatethe lever by an engine directly connected thereto. The engine iscontrolled by a handlever within convenient reach of the operator. Inthis manner the most direct and the quickest action is obtained.

Iny the accompanying drawings, like letters referring to like partsthroughout, Figure 1 is a side elevation of my invention in position foruse. Fig. 2` is a plan view of the same, and Fig. 3 is a front view ofthe pivoted mast detached. I

A represents the basement, B the workingiioor, and C the ceiling oroverhead framework, of an ordinary saw-mill.

Dis an upright post or mast pivoted so as to freely turn in thehorizontal plane. As shown, this mast is composed of separate pieces dand d', securely bolted together at top and bottom through end blocks dd. There is thus left a clear space between the side bars CZ and d',which serve as a crosshead guide, as hereinafter stated. The upper endpiece d is provided with a pintle E, adapted to engage with the socketor seat E in the overhead beam C. The lower end'piece cl" is providedwith a hole through its vertical oenter. On the lower end of the mastsurrounding its central opening is secured an annular metallic flange orbearing-plate F, cast integral with the block cl".

To the ioor B, in proper position to engage with the bearing-plate F, issecured a corresponding annular casting or base-plate G, having avertical flange g. The mast rests upon the bearing-plate G below and isheld from displacement by the pintle E and the 5o socket E above. Itisthus free to turn in the horizontal plane on these bearings as pivots.

H I-I are a pair of horizontal arms rigidly secured to the oppositefaces of the mast D. 5 5 7i are braces for the same.

K is the log-loading lever. This is pivotally secured at about itscentral point by pivot-pin L, between the outer ends of the arms II H.The inner end of this lever is 6o approximately in line with the axis ofthe mast D. Its outer end is 'provided with a grappling device M,adapted to handle logs.

N is a cross-head movable between the bars d d as guides.

P is an upright slide-valve reciprocating engine located, as shown, inthe basement A, directlyinline with the axis of the mast D. Thepiston-rod p of this engine passes up through the floorB and the hole inthe end block of 7o v the mast D and is attached at its upper end to thecross-head N.

Q is a connecting-rod uniting the crosshead N and the inner end of thelog-loading lever K.

R is a hand-lever pivoted to the floor B in convenient position for theoperators use, and R is a connection from the same to the valve of theengine P.

S S represent logs, and T is one of the sup- 8o ports for the same.

Theoperation is evident from the description. The inner end of thelog-loading lever being directly connected to the piston of the engine,is moved up and down at the will of the operator through thevalve-operating lever R. This gives the necessary movement to raise orlower the logs. The mastD freely turns on its pivots, the piston of theengine turning within its cylinder, and this gives 9ol the necessarymovement to swing the logs wherever desired in the horizontal plane.

It will be readily understood that the specie construction of the mastmaybe different than herein shown. The engine might be also elsewherelocated as long as the piston is directly attached to the log-loadinglever.

I use steam as my motive power; but of course it` will be understoodthat air or liquid under pressure might equally Well be employed.

Vhat I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

l. The combination, with a pivoted mast provided with verticalcross-head guides and a rigid horizontal arm, of a log-loading leverpivoted to said arm, a cross-head movable in said guides, an enginehaving its piston connected to said cross-head, and a connectingrod fromsaid cross-head to said log-loading lever, substantially as described.

2. The combination, with a pivoted mast provided with verticalcross-head guides and a rigid horizontal arm, of a log-loading leverpivoted to said arm, a cross-head movable lengthwise of said guides,areciprocating engine mounted in XeCl supports in line with said guides,having its piston connected to FRED.
